Sioux Chief 521-729 Copper-Plated Double Carrier Bracket with Reversible Slots, 16-GA

The Sioux Chief 521-729 is a 16-GA copper-plated double carrier bracket engineered as a flush valve stubout bracket for wall-hung water closets. It supports the water pipe for the flush valve 26-1/2" above the floor, giving plumbers a dependable rough-in reference point when roughing in commercial and institutional restroom installations. The extruded design runs the entire length of the bracket for maximum strength and rigidity, and washers are included for a complete, ready-to-install assembly. This is a behind-the-wall rough-in component intended for installation before the finished wall surface goes up, positioning the flush valve supply at the correct height relative to the floor.

Key Features

  • Mounting Height: Supports water pipe for the flush valve 26-1/2" above the floor for consistent, code-anticipated stubout positioning on wall-hung water closet installs.
  • Durable Construction: Fabricated from 16-GA copper-plated steel for a rigid, corrosion-resistant carrier that holds its position during rough framing and wallboard installation.
  • Double Carrier Configuration: Dual-bracket design distributes support across the flush valve stubout, reducing flex and keeping the water pipe aligned through the rough-in and finish stages.
  • Reversible Slots: Slotted bracket design allows the carrier to be reversed and adjusted on the job, giving installers flexibility when positioning the stubout for different wall-hung fixture layouts.
  • Extruded Full-Length Design: The extrusion runs the entire length of the bracket, adding strength and rigidity compared to shorter stamped supports, so the bracket resists bending under load.
  • Washers Included: Ships complete with washers so the bracket is ready to install without sourcing additional small hardware on site.

Sioux Chief 521-729 – Frequently Asked Questions

1) What is the Sioux Chief 521-729 carrier bracket actually used for?
It is a behind-the-wall rough-in bracket that holds the flush valve supply pipe for a wall-hung water closet, setting that pipe 26-1/2 inches above the floor. You install it on the framing before the finished wall goes up, so the stubout lands at a repeatable height on every fixture in a restroom run.
2) Does the 521-729 bracket support the water closet itself, or just the flush valve pipe?
Just the pipe. The 521-729 is a flush valve stubout bracket, not a fixture carrier. It supports the water pipe feeding the flush valve at 26-1/2 inches off the floor. The weight of a wall-hung bowl has to be carried by a separate fixture carrier.
3) Can the Sioux Chief 521-729 be adjusted or flipped on the job if the stubout location changes?
Yes. The slots are reversible, so the carrier can be turned around and shifted to suit different wall-hung fixture layouts rather than being locked to one orientation.
4) How heavy a gauge is the 521-729 bracket, and will it stay put during wallboard install?
It is 16-GA copper-plated steel with an extrusion that runs the full length of the bracket, which is what keeps it from bending or drifting while framing and wallboard go in. Full-length extrusions are stiffer than shorter stamped supports under the same load.
5) Do I need to buy washers or extra hardware with the Sioux Chief 521-729?
Washers ship with the bracket, so it arrives as a complete assembly. You still supply whatever fasteners suit your framing and the pipe clamping method your rough-in calls for.
6) Is the Sioux Chief 521-729 sold individually or in a pack?
It is packaged 5 each, so one order covers five rough-in locations. That suits a multi-stall commercial or institutional restroom where every water closet needs the same stubout height.
7) Why a copper-plated bracket instead of plain or galvanized steel for a water closet rough-in?
The copper plating gives corrosion resistance on a part that gets sealed permanently behind a finished wall, where you cannot inspect or replace it later. The base material is steel at 16-GA.
8) What does the double carrier configuration on the 521-729 do differently from a single bracket?
The dual-bracket arrangement spreads support across the flush valve stubout instead of loading one point. That cuts flex and keeps the supply pipe aligned from rough-in through finish, which matters when the valve body gets threaded on later.
9) What is the Sioux Chief part number and MPN for this double carrier bracket?
Sioux Chief 521-729, and the manufacturer part number is the same, 521-729. Specify it by that number when standardizing stubout heights across a restroom package.
